So from what I have gathered, text posts on the network are not automatically translated. Every one is written in a language actually known by a player. For the most part, I'm assuming that's English unless otherwise specified by a player.

Sokka speaks and writes in Chinese. So my assumption is that, for the most part, most my character wouldn't be able to read said messages? Is that correct? Or is there such a thing as a language-neutral text network message, and only if [English] is specified is it incomprehensible?

As a follow-up, is Malicant speaking English? Language-neutral? Or whatever it would be that Sokka could understand?
